our patient has a condition called hyporenin hypoaldosterone, which results in low levels of aldosterone. [Note: the NORMAL actions of aldosterone in the kidney is to excrete K+ and reabsorb Na+.] This condition results in excess K+ in the blood (lab results showed 7.5 mmol/L K+ in the blood) and low levels of Na+ in the blood (lab results showed 110 mmol/L Na+ in the blood). Answer the following questions. For the calculation, show your work. A. What is the medical term for high blood K+ levels? B. Calculate the Equilibrium Potential for K+ using the above lab value and a normal ICF K+ level of 145 mmol/L. C. What is the normal RMP for ventricular cardiac myocytes? E. What effect can this condition have on the heart?
